To allwhom it 1mg concern Be it known that 1, Wmlrin momma, a resident of Chicago, in the county of Cook to conveniently, cheaply and rapidly :pplyl in liquid cnsrsei or other coating materi regulated quantities and evenly to the hoofi' or eyes, and to fix the some on said articles, and to discharge the completed articles by a. continuous operation.

The invention consists in the method and ap arstushereinafter described and particula! y pointed out.

In the accompanying drawing which illustrates the invention and forms part offthe specification,-Fi re 1 is an elevation partly in section s owing the parts of the apparatus arranged and connected for use; Fig. 2 is an enlarged partial section showing feed and spacing devices, with several eyes to be fed onto a wire; Fig. 3 is a. side view of a. stop andspscing device Fig. 4 is apartiai side view, and a cross section, of a feed barused for hooks; Fig. 5 is an ed e view of an eye (or hook) discharging whee Fi 6 is a partial edge view of a modified disc arging wheel showing its operation on hooks Fig. 7 is an enlar ed view of the foot of the feed bar, eyes t ereon being in section, the eyes being held back by the lower tooth of the spacing device.

Heretofore attempts have been made to enamel hooks and eyes but without good results, for the reason that it has not been found practicable with old methods to evenly distribute the enamel in the riglht quantity on such articles, there being 0 jectionable accumulations of material at certain points on them.

By this imgrovement the hooks 'or eyes.

are not dip in a bath of enamel, or the like, but suc material (of any selected color) is sprayed in finely divided condition onto them, which gives a. thin, even coating without objectionable gathering of dro s or quantities of the coating material at t e bottom hes a step 10 of a little greater he of the articles, or between closely adjacent ports of the wire, as between the two parallel members of a. hook shank, or in'a thread-receiving ice of on eye.

Numeral i denotes a. rotatable supply spool on which is wound a long fine wire 2 which extends to e receivingspool 3 at the opposite end of the apparatus, and suitably driven, as by a belt 4 from an electric motor 5. v

6' indicates a tank ha which rial which will coat the wire and tend to prevent the sprayed enamel from adhering to guide rollers 'tl'ie wire, or if some does adhere will render its rernoval easy. a Paraflin, heated in suitable manner, as by a steam pi e 6*,is sniteble for the purpose named. piece of felt 7 s1- the like rubs against the outgoing wire to remove excess of material.

in inclined feed bar or plate is show at 8. This is supported in a vertical plane, end is snficientiy thin to ties between the shank and the hook end 0 a hook, or between the ends of an eye. 7 Preferably the width of this bar or plate is greater than the length of the hooks or eyes to be treated.

The lower edge of piste 8 has a strengthenilnglpart 9 which may be secured to a support.

' .2 art isafis eonthelowered e of th? le ie itself. ln fiigl. g bar 9* aving ll es and swing a groovein which part 8 is he d. Bar 8 at its lower and t then the diameter of wire usedm making e books or eyes; The step terminates in an end 11 prpijecting close to and just above wire 2, an of roster inclination than the main part of the ar. Eyes are hung on this bar 8 by hand or otherwise as indicated in Fig. 1, or hooks es in Fig. 4, and they tend to slide down thereon by gravity.

Adjacent the step 10 and above it is a spacing device comprising a toothed disk 12 near the step so that when one of its teeth is in'front of the step the eyes (or hooks) are held back thereby; but a space or notch allows oneto pass. The device comprises also a larger toothed disk 13, the teeth and 'notshes of which break joints with those of disk'12, and which stands over the end 11, snd'when a tooth is directly in front of it the eye which has been last deposited on said end b disk 12 is held-from moving forward on to t e wire. but when the disk moves forward ids wire 2 through a ath of a. mate- 4 it is a thicker Ill b r a notch over said end 11 the eye is released and drops onto the moving wire 2.

The teeth and notches of the connected disks 12 and 13 are so arran ed that the lower 10 tooth through the me ium of the eye last a vanced onto end 11 holds all the eyes on the bar 8 until a tooth of disk 12 comes into position to hold them, when the long tooth moves out of the way and allows the'e'ye on end 11 to slip from the steeply inclined end onto wire 2, and so on repeatedly.

In Fig. 7 the bottom long tooth is holding all the eyes back and a tooth on disk 12 is about to come into place to hold them.

The distance between successive hooks or eyes will depend on the s eed of movement of the wire 2, and the spee at which the s acing device is driven, for example, by pu eys 14, 15 and belt 16.

17 denotes a s raying chamber having openings in its en through which wire 2 with spaced eyes thereon moves. In the chamber is a su pl 18 of colored enamel or the like, from w 10 rises a pipe 19 open below the liquid, and provided with terminal spraying nozzles 20, one above and one below wire 2. 21 is a pipe extending from any suitable source of compressed air, as an air pump 22, and terminatinglin said nozzles to spray the enamel onto t e articles on the wire 2 between them. Over the openings in the tank are hoods 23 to partly cover the wire except in the central part, and to prevent escape of sprayed material. The air pump may be driven b .a belt 24 from the motor 5. 25 denotes a rying or baking chamber or device comprising an open ended tube 26 of suitable length and size through which the wire 2 with its spaced and sprayed articles travels, and heating means, preferably a suitably rotected heating coil 27 thereon.

If desired a vent tube 28 for vapor may be provided.

30 denotes an eye (or hook) removing-device. 'Its edge is thin to extend between the thread-receiv loops of an e e, or between the shank and t e hook end 0 a hook. The periphery is ooved, and wire 2 passes over the wheel on 1ts way to the s 001 3 as shown.

At a distance less than the ength of an eye (or hook) from the peripher of said wheel is a shoulder 31 forming a t ickening of the wheel. There may be such a shoulder on both sides, as in Fig. 5 or on one side as in Fig. 6. As the wire advances the forward e e (or hook) at its lower end strikes the thick part of said wheel, is tilted thereb and finally dro s or is forced offend fa ls into a receptac e. Y
